Key Ingredients

Here’s what powers the COSRX The Hyaluronic Acid 3 Serum 20ml:

Hyaluronic Acid (3%)
This moisture-binding ingredient helps attract water to the skin and keep it hydrated for longer periods. It gives skin a plumper, fresher appearance while helping reduce dryness and rough texture.

Ceramide NP
Ceramides help reinforce the skin barrier and prevent moisture from escaping. They’re especially helpful for skin that feels dry, weakened, or sensitive from dehydration.

Amino Acid Complex
Amino acids help maintain skin softness and support overall skin health. They also help improve moisture retention and comfort.

Sodium Hyaluronate
A smaller form of hyaluronic acid that absorbs more easily into the skin. It helps provide lightweight hydration without heaviness.

Panthenol (Pro-Vitamin B5)
Panthenol helps soothe dryness and supports the skin barrier while adding an extra layer of hydration.

Allantoin
Known for its calming properties, allantoin helps soften skin and reduce feelings of irritation or tightness.

Best For:

• ✅ Dry Skin — intense hydration
• ✅ Dehydrated Skin — moisture retention
• ✅ Sensitive Skin — gentle formula
• ✅ Combination Skin — lightweight hydration

Targets These Concerns:

• Dryness
• Dehydration
• Tight, rough texture
• Weak moisture barrier
• Dull-looking skin

Not Recommended For:

  3. Pat Gently — Press into skin until fully absorbed.
  4. Seal Moisture — Follow with moisturizer to lock hydration in.

    আমি প্রায় ২ সপ্তাহ ধরে COSRX The Hyaluronic Acid 3 Serum 20ml ব্যবহার করছি আর স্কিন অনেক বেশি হাইড্রেটেড লাগছে। আগে মুখ ধোয়ার পর টান টান লাগতো, এখন অনেক কমে গেছে। সিরামটা খুব হালকা আর স্টিকি না। রাতে ব্যবহার করলে সকালে স্কিন অনেক ফ্রেশ লাগে।
